Horizontal composite electricity supply structure

ABSTRACT

The present disclosure relates to a horizontal composite electricity supply structure, which comprises a first insulation layer, a second insulation layer, two patterned conductive layers, and a plurality of electrochemical system element groups. The two patterned conductive layers are disposed on the first and second insulation layers, respectively. The plurality of electrochemical system element groups are disposed between the first insulation layer and the second insulation layer, and connected serially and/or parallelly via the patterned conductive layers. The electrochemical system element group is formed by serially connecting one or more electrochemical system elements. Each electrochemical system element includes a package layer on the sidewall, so that their electrolyte systems don&#39;t circulate. Thereby, the high voltage produced by connection will not influence any single electrochemical system element nor decompose their electrolyte systems. Hence, serial and/or parallel connections can be done concurrently in the horizontal composite electricity supply structure.

FIELD OF THE DISCLOSURE

The present disclosure relates generally to an electricity supplystructure, and particularly to a high-voltage, high-capacity, andthree-dimensionalized horizontal composite electricity supply structureby serially connecting electrochemical system elements and concurrentlyconnecting parallelly and/or serially electrochemical system elementgroups in the electricity supply structure.

BACKGROUND OF THE DISCLOSURE

In recent years, due to the exhaustion of petrochemical fuels and theprevalence of the consciousness of environmental protection, people areforced to rethink how to balance between living convenience andenvironmental protection for those objects using petrochemical fuels asthe power source and exhausting massive greenhouse gases. Cars, asimportant transportation vehicles, become one of the primary objects tobe inspected. Accordingly, under the global trend of energy saving andcarbon reduction, many countries worldwide set car electrification as animportant target for carbon dioxide reduction. Unfortunately, electriccars face many problems in practical applications. For example, thecapacity of electricity supply elements limits the endurance.Consequently, more batteries should be connected in series or parallellyfor increasing the capacity and thus extending the mileage.

To reduce the car weight for extending mileage, the secondary batterieswith high energy density and light weight, such as lithium-ion secondarybatteries, become the best choice for the battery of electric cars.Nonetheless, how to assemble multiple lithium-ion secondary batteries toform a safe and stable power source has become an urgent challenge forpeople.

First, please refer to FIG. 1A and FIG. 1B, showing the common method.After multiple sets of battery elements 71 are connected parallelly, thehousing 72 is used for sealing and forming the battery cell 73. Then theconductive leads 74 protruding from the housings 72 of the battery cells73 are connected in series externally for reaching a sufficient voltage,giving the battery module 75 for cars. According to another method, asingle housing 72 is adopted for covering multiple battery elements 71,as shown in FIG. 2A and FIG. 2B. In other words, internal seriesconnection is adopted for increasing the voltage of the battery cell 76.Then multiple battery cells 76 are connected parallelly and externallyfor reaching sufficient capacity for forming the battery module 77 forcars. Unfortunately, current electrolyte can only sustain around 5volts. Besides, it is difficult to form a closed system for electrolytedue to internal structural problems. Once the voltage exceeds thesustainable range of the electrolyte, the electrolyte will decompose andmake the battery module 77 fail. Even worse, the battery might explode.Accordingly, there is no such product in the market.

According to the US patent application No. 2004/0091771, adjacentbattery modules share a common electricity collecting layer. By usingthis method, the problem of electrolyte decomposition as described abovecan be solved. Unfortunately, owing to the series connection to thecommon electricity collecting layer, the design will be less flexible.Only internal series connection can be adopted. To form a batterymodule, external parallel connection of a plurality of battery cellsstill should be adopted.

Furthermore, according to a composite battery cells of Taiwan patentapplication No. 106136071, series and parallel connections can be doneinside battery cells directly for giving high-voltage andhigh-unit-capacity battery cells, eliminating the drawbacks of lowerperformance and reduced capacity density due to external connectionaccording to the prior art. Unfortunately, according to the technology,the electricity supply element group achieves high capacity and highvoltage by vertically stacking a great number of electricity supplyelements for series and/or parallel connections.

Nonetheless, while facing puncture of metal objects, the high voltagedrop caused by puncture is unavoidable extremely dangerous for fullysolid, pseudo solid (solid/liquid), or liquid electrolyte systems. It isparticularly dangerous for battery cells formed by vertically stackingmassive electricity supply elements internally.

According to the drawbacks, the present disclosure provides a novelhorizontal composite electricity supply structure for avoiding safetyconcerns caused by puncture of battery elements by metal objects.

SUMMARY

An objective of the present disclosure is to provide a horizontalcomposite electricity supply structure, which adopts series and/orparallel connections in the horizontal direction to connect electricallymultiple electrochemical system element groups for reducing the numberof vertically stacked electrochemical system elements and avoidingsafety problems caused by punching by metal objects.

Another objective of the present disclosure is to provide a horizontalcomposite electricity supply structure. A first insulation layer and asecond insulation are disposed at the top and bottom, respectively.Multiple electrochemical system element groups extending horizontallyand connected serially and/or parallelly are disposed between the firstand second insulation layers. By using the first and second insulationlayers, the potential damages caused by punctures on battery cells byexternal metal objects can be prevented.

Another objective of the present disclosure is to provide a horizontalcomposite electricity supply structure. There is no electrochemicalreaction between adjacent electrochemical system elements except chargetransfer. Thereby, electricity supply elements will not limit to themaximum voltage of allowance of electrolyte, and could connect in seriesand/or parallel way. Hence, the capacity density and voltage can beimproved.

Still another objective of the present disclosure is to provide ahorizontal composite electricity supply structure. Multiple channels areformed between adjacent electrochemical system element groups, acting aspaths for heat dissipation.

A further objective of the present disclosure is to provide a horizontalcomposite electricity supply structure. The electricity collectinglayers between adjacent electrochemical system elements are shared forconnection. The contact area is much larger than the one by nickel platesoldering according to the prior art. Thereby, the internal resistanceof the electrochemical system element group can be reducedsubstantially. The performance of the power module formed by theelectrochemical system element groups hardly loses. In addition, becausethe reduction of resistance, the charging and discharging speedsincrease significantly, and the heating problem is reducedsignificantly. Then the cooling system of the electrochemical systemelement group can be simplified and can be managed and controlledeasily. Thereby, the reliability and safety of the overall compositeelectricity supply structure can be enhanced.

To achieve the above objectives, the present disclosure provides ahorizontal composite electricity supply structure, which comprises afirst insulation layer, a second insulation layer, two patternedconductive layers, and a plurality of electrochemical system elementgroups. The second insulation layer is disposed opposing to the firstinsulation layer. The two patterned conductive layers are disposed onthe surface of the first and second insulation layers, respectively, andfaced to each other. The plurality of electrochemical system elementgroups are disposed between the first insulation layer and the secondinsulation layer, and connected serially and/or parallelly via thepatterned conductive layers. Each electrochemical system element groupis formed by one or more electrochemical system elements. A packagelayer is deposited on the periphery of each electrochemical systemelement, so that there is no circulation between adjacent electrolytesystem elements except charge transfer. Thereby, electricity supplyelements will not be limited to the maximum voltage of allowance ofelectrolyte, and could connect in series and/or parallel at same time.Each electrochemical system element comprises an isolation layer, twoactive material layers, and an electrolyte system. The two activematerial layers are disposed on both sides of the isolation layer,respectively. The electrolyte system is disposed in the active materiallayers. The electrochemical system elements on the two outermost sidesof each electrochemical system element group adopt the patternedconductive layers as the electricity collecting layers.

In the following, concrete embodiment are described in detail forunderstanding the objective, technologies, feature, and the effectsprovided by the present disclosure.

DETAILED DESCRIPTION

Given the safety problem caused by puncture on multiple electrochemicalsystem elements stacked vertically and connected serially by metal sharpobjects for the demand of high voltage and high capacity, the presentdisclosure provides a novel horizontal composite electricity supplystructure to solve the puncture problem.

The present disclosure mainly discloses a horizontal compositeelectricity supply structure, which comprises a plurality ofelectrochemical system element groups. The electrochemical systemelement group comprises one or more mutually serially and/or parallellyconnected electrochemical system elements. Then, after multipleelectrochemical system element groups are mutually connected seriallyand/or parallelly via the patterned conductive layers, a firstconductive terminal and a second conductive terminal are connected toelectrochemical system element groups to form the composite electricitysupply structure. In other words, inside the composite electricitysupply structure, series and parallel connections can be doneconcurrently. The electrochemical system elements forming theelectrochemical system element group according to the present disclosuredon't share electrolyte systems each other. Figures are used for furtherdescription. The above composite electricity supply structure can be anysupply element capable of storing energy and supply external devices,such as batteries or capacitors.

First, please refer to FIG. 3, which shows a schematic diagram of thehorizontal composite electricity supply structure according to the firstembodiment of the present disclosure. As shown in the figure, thehorizontal composite electricity supply structure 10 according to thepresent disclosure mainly comprises a first insulation layer 12, asecond insulation layer 14, a patterned conductive layer 16 (16 a, 16 b16 c), another patterned conductive layer 18 (18 a, 18 b), and aplurality of electrochemical system element groups 20. The secondinsulation layer 14 is opposing to the first insulation layer 12 in thehorizontal direction. The patterned conductive layer 16 is located on afirst surface 12 s extending horizontally inside the first insulationlayer 12. The patterned conductive layer 18 is located on a secondsurface 14 s extending horizontally inside the second insulation layer14. The patterned conductive layer 16 is opposing to the patternedconductive layer 18. The material of the first and second patternedconductive layers 16, 18 can be selected from the group consisting ofmetals and any conductive materials. The plurality of electrochemicalsystem element groups 20 are sandwiched between the first and secondinsulation layers 12, 14 and connected electrically to the differentpolarity via the patterned conductive layers 16, 18 for forming seriesconnection. For convenience, a battery is adopted in the followingembodiment for description. A person having ordinary skill in the artknows well that the embodiment is not used to limit the scope of thepresent disclosure.

The electrochemical system element group 20 as described above is formedby one or more electrochemical system elements 22. For example, in FIG.3, the horizontal composite electricity supply structure 10 is formed byserially connecting four electrochemical system element groups 20 witheach one of the electrochemical system element groups 20 formed by anelectrochemical system element 22. The structure of the aboveelectrochemical system element 22 is shown in FIG. 4A. Eachelectrochemical system element 22 includes a first active material layer225, an isolation layer 226, a second active material layer 227, and anelectrolyte system disposed in the first active material layer 225 andthe second active material layer 227. The first active material layer225 is connected to the electricity collecting layer 16, and the secondactive material layer 227 is connected to the other electricitycollecting layer 18. The isolation layer 226 is located between thefirst active material layer 225 and the second active material layer227. A package layer 23 is disposed on the periphery of eachelectrochemical system element 22 so that the electrolyte system ofadjacent electrochemical system elements do not circulate except chargetransfer. Without electrochemical reaction, electrochemical systemelements will not limit to the maximum voltage of allowance ofelectrolyte, could connect in series and/or parallel at same time.

The material of the isolation layer 226 with micro holes allowing ionsto passing through can be selected from the group consisting of polymermaterials, ceramic materials, and glass fiber materials. The micro holescan be penetrating holes, nonlinear holes, or even made by porousmaterials. In addition, porous ceramic insulative materials can bedistributed inside the micro hole of the substrate. The ceramicinsulative materials can be formed by materials such as micrometer- ornanometer-grade titanium dioxide (TiO₂), aluminum oxide (Al₂O₃), silicondioxide (SiO₂), or alkylated ceramic particles. The ceramic insulativematerials can further include polymer adhesives, such as polyvinylidenefluoride (PVDF), polyvinylidene fluoride-co-hexafluoropropylene(PVDF-HFP), polytetrafluoroethylene (PTFE), acrylic acid glue, epoxy,polyethylene oxide (PEO), polyacrylonitrile (PAN), or polyimide (PI).

The electrolyte system is disposed in the first and second activematerial layers 225, 227. The form of the electrolyte system can beselected from the group consisting of liquid state, pseudo solid state,gel state, solid state or combinations thereof. The active materials ofthe active material layers 225, 227 can convert chemical energy toelectrical energy for usage (supplying electricity) or electrical energyto chemical energy for storage (charging), and can achieve ionconduction and transport concurrently. The generated electrons can beled outward via the adjacent electricity collecting layers.

The material of the package layer 23 can include epoxy, polyethylene,polypropylene, polyurethane, thermoplastic polyimide, silicone, acrylicresin, or ultraviolet-hardened glue. The package layer 23 is disposed onthe periphery of the electrochemical system element 22 with two endsglued to the electricity collecting layers on both sides of theelectrochemical system element 22. According to the present embodiment,the package layer 23 is glues to the patterned conductive layers 16, 18for sealing the electrolyte system between the patterned conductivelayers 16, 18 and the package layer 23 for avoiding leakage andcirculation with the electrolyte system of other electrochemical systemelements 22. Thereby, the electrochemical system element 22 is anindependent and complete electricity supply module.

To improve the sealing effect of the package layer 23, the package layer23 can be designed to have three layers. Please refer to FIG. 4B. Thetop and bottom layers 23 a, 23 b are modified silicone and the middlelayer is a silicone layer 23 c. The modified silicone layers 23 a, 23 bon both sides are modified by adjusting the ratio of addition andcondensation silicone for gluing heterogeneous materials. By using thedesign, the cohesion at the interface is increased. At the same time,the overall appearance is more complete and the production yield isimproved. Furthermore, the design can block permeation of moisture.Internally, the silicone layer 23 c acting as the main structure canblock damages caused by polar solvent and plastic agent. Thereby, theoverall sealing structure can be more complete.

In addition, for easier description and identification, theelectrochemical system elements 22 in the figures for illustrating thehorizontal composite electricity supply structure use simple positiveand negative symbols to identify the positive and negative electricalpolarities for illustrating the electrical properties, instead ofplotting the detailed components of the electrochemical system element22 as shown in FIG. 4A and FIG. 4B. A person having ordinary skill inthe art should know the meanings of the positive and negativepolarities. Hence, the details will not be described again.

As shown in FIG. 5A and FIG. 5B, a single electrochemical system elementgroup 20 is formed by serially connecting a plurality of verticallystacked electrochemical system elements 22 in opposite polarities. Theouter sides of the electrochemical system elements 22 on the outermostsides of the electrochemical system element group 20 use the patternedconductive layers 16, 18 directly as the electricity collecting layers.Two stacked electrochemical system elements 22 use a common electricitycollecting layer 19 for isolating and collecting electrons. Thereby, thesecond active material layers 227 and the first active material layers225 of adjacent electrochemical system elements 22 are connectedelectrically through the common electricity collecting layer. Forexample, as shown in the figures, the first active material layer 225 isthe positive layer, and the second active material layer 227 is thenegative layer. Then the second active material layer 227 of the topmostelectrochemical system element 22 contacts the common electricitycollecting layer 19; the first active material layer 225 of the adjacent(bottom) electrochemical system element 22 contacts the commonelectricity collecting layer 19. By stacking sequentially, theelectrochemical system element group 20 in series connection can beformed. Because the electrolyte systems of each electrochemical systemelement 22 do not circulate, there is no electrochemical reactionsbetween adjacent electrochemical system elements 22 except chargetransfer (i.e., ions will not transfer or conduct). Therefore, evenmultiple electrochemical system elements 22 are connected serially toform a high voltage, the electrolyte system inside individualelectrochemical system element 22 will not be influenced. The internalvoltage is still maintained at the voltage of a single electrochemicalsystem element 22. Thereby, it will not limit to the maximum voltage(generally, around 5 volts) of the electrolyte system, the electricitysupply element group 20 with high voltage could be formed by serialstacking multiple electricity supply elements 22. In addition, theelectricity collecting layers between adjacent electrochemical systemelements 22 are shared for connection. The contact area is much largerthan the one by nickel plate soldering according to the prior art.Thereby, the internal resistance of the electrochemical system elementgroup can be reduced substantially. The performance of the power moduleformed by the electrochemical system element groups hardly loses.Besides, as the reduction of resistance, the charging and dischargingspeeds increase significantly, and the heating problem is reducedsignificantly. Then the cooling system of the electrochemical systemelement group can be simplified and can be managed and controlledeasily. Thereby, the reliability and safety of the overall compositeelectricity supply structure can be enhanced.

Due to the requirement of contacting positive and negative electrode(active material layers 225,227) concurrently, the materials of thepatterned conductive layers 16, 18 and/or the common electricitycollecting layer 19 as described above should be able to tolerate highand low voltages and no oxidation reaction should occur. For example,the materials include stainless steel (SUS) or graphite. Furthermore,the materials can be the metal powders selected from the groupconsisting of aluminum, copper, titanium, nickel, stainless steel, andthe alloys thereof. By spraying or calendering the metal powers mixedwith adhesive, the patterned conductive layers 16, 18 and/or the commonelectricity collecting layer 19 can be manufactured.

The horizontal composite electricity supply structure 10 according tothe present disclosure further comprises a first conductive lead 24 anda second conductive lead 26. In FIG. 3, the first conductive lead 24 andthe second conductive lead 26 are connected electrically to thepatterned conductive layer 16 concurrently. Of course, they can beconnected to different patterned conductive layers. For example, thefirst conductive lead 24 is connected electrically to the patternedconductive layer 16 and the second conductive lead 26 is connectedelectrically to the patterned conductive layer 18, as illustrated inFIG. 6.

Furthermore, the first conductive lead 24 and the second conductive lead26 can be formed integrally with the patterned conductive layers 16, 18connected electrically with them. As shown in FIG. 7, a portion of thepatterned conductive layer 16 a is extended to the outside of the firstinsulation layer 12 and acting as the first conductive lead 24; aportion of the patterned conductive layer 16 c is extended to theoutside of the first insulation layer 12 and acting as the secondconductive lead 26. In other words, during the process of patterning,the patterns of the first conductive lead 24 and the second conductivelead 26 are reserved.

When the first and second conductive leads 24, 26 are formed notadopting the integral method, the materials of the first and secondconductive leads 24, 26 can be different from those of the patternedconductive layers 16, 18. In addition, direct contact can be formed bysoldering with or without soldering material, or by melting method.Alternatively, conductive silver glue or conductive cloth can beadopted.

Under the architecture of the horizontal composite electricity supplystructure according to the present disclosure, to increase the totalcapacity or total voltage of the battery module, the only thing to do isto perform external series/parallel connection of multiple horizontalcomposite electricity supply structures 10 by using the first and secondconductive leads 24, 26. Then the total capacity or the total voltage ofthe battery module can be increased. For example, by externallyconnecting serially multiple horizontal composite electricity supplystructures 10, the total voltage can be increased, as shown in FIG. 8A.By externally connecting parallelly multiple horizontal compositeelectricity supply structures 10, the total capacity can be increased,as shown in FIG. 8B.

To increase the voltage of a single horizontal composite electricitysupply structure, simply add the electrochemical system element group.For example, as shown in FIG. 9, compared to FIG. 3, two electrochemicalsystem element groups 20 are added and connected serially via thepatterned conductive layers 16, 18.

Please refer to FIG. 6. This horizontal composite electricity supplystructure 10 uses two electrochemical system element groups 20 to form anew set 28 by parallelly connecting the same polarity via the patternedconductive layers 16, 18. Then the new set 28 is used as an element. Byconnecting the opposite polarities via the first and second patternedconductive layer 16, 18, a series connection is formed. Besides,although the new set 28 can be integrated into an electrochemical systemelement, the number of gaps 30 can be increased if they are separated.

Please refer to FIG. 10. The gaps between connected electrochemicalsystem element groups 20 can act as the heat dissipation channels forthe horizontal composite electricity supply structure 10. Multiplepositioning members 32 are formed on the surfaces of the firstinsulation layer 12 and/or the second insulation layer 14 facing theelectrochemical system element groups 20. The positioning members 32 areexposed outside the patterned conductive layers 16, 18 for limiting thelocations of the electrochemical system element groups 20. For example,the existence of the positioning member 32 can assist to fix thepatterned conductive layers 16, 18 to the correct location. Furthermore,a fluid, such as gas or liquid, can be added into the gaps forincreasing the heat dissipation effect.

The benefits of the present disclosure will be further described. Forexample, according to the composite electricity supply structure of theTaiwan patent application No. 106136071, 24 electrochemical systemelements are vertically and serially connected to give a voltage valueof 24*4.2 volts. By adopting the horizontal composite electricity supplystructure according to the present disclosure given the same voltagevalue and number of electrochemical system elements, 24 singleelectrochemical system elements can be connected in opposite polaritieshorizontally via the conductive layers 16, 18, as shown in FIG. 9.Alternatively, 12 pairs of stacked electrochemical system elements canbe connected in opposite polarities horizontally via the patternedconductive layers 16, 18, as shown in FIG. 11. Alternatively, anothernumber of stacked electrochemical system elements can be adopted. Underthis architecture, when a sharp metal object 34 punctures the horizontalcomposite electricity supply structure from the outside, instead of the24 vertically stacked electrochemical system elements, the puncturedobject will be only a few stacks. Thereby, the danger of puncture on amassive serially stacked electrochemical system elements can be avoidedeffectively.

Next, when the electrochemical system element group 20 is formed by twoor more electrochemical system elements 22, the serial and/or parallelconfigurations of the plurality of electrochemical system elements 22are described.

Please refer to FIG. 5A. In the figure, multiple electrochemical systemelements 22 in the electrochemical system element group 20 are connectedelectrically in series and opposite polarities. Please refer to FIG. 12,multiple electrochemical system elements 22 in the electrochemicalsystem element group 20 are connected electrically in parallel and thesame polarity. Please refer to FIG. 13, multiple electrochemical systemelements 22 in the electrochemical system element group 20 are connectedin a mixed method by first parallel and then series connections. Pleaserefer to FIG. 14, multiple electrochemical system elements 22 in theelectrochemical system element group 20 are connected in a mixed methodby first series and then parallel connections. In the mixed connectionmethod as described above, suitable wires 78 can be used to connect thepositive/negative terminals (the electricity collecting layers) of theelectrochemical system element 22 to the corresponding patternedconductive layers. In addition, for convenient connection of the wires78 and the electricity collecting layers of the electrochemical systemelements 22 or the common electricity collecting layer 19, a projectivetab 79 can be disposed at the electricity collecting layers, as shown inFIG. 15. The protruding projective tab 79 can be used for electricityconnecting.

To sum up, the present disclosure provides a horizontal compositeelectricity supply structure, which comprises multiple electrochemicalsystem element groups. The electrochemical system element groups areserially and/or parallelly connected internally in a horizontalextension method via the patterned conductive layers for reaching acertain voltage and capacity. In addition, external series and/orparallel connections of multiple horizontal composite electricity supplystructures can be done via the first and second conductive leads of thehorizontal composite electricity supply structures. Furthermore, thehorizontal composite electricity supply structure according to thepresent disclosure comprises a first and a second insulation layers atthe top and bottom for effectively preventing potential damages causedby puncture of metal objects on the electricity supply structure.

Moreover, in addition to blocking puncture effectively, the first andsecond insulation layers 12, 14 according to the present disclosure canact as the blocking layers for electrical contact between the patternedconductive layers when multiple electricity supply structures 10 areexternally connected serially and/or parallelly.

Accordingly, the present disclosure conforms to the legal requirementsowing to its novelty, nonobviousness, and utility. However, theforegoing description is only embodiments of the present disclosure, notused to limit the scope and range of the present disclosure.
